I was going to retort but he's right. There are so very few Democrats willing to fight for... well, anything. They roll over to the GOP every time. (probably because they're not nearly as far-left as conservatives seem to think they are)

The Constitution says Obama must get authorization from Congress but the War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30 day withdrawal period, without an authorization of the use of military force or a declaration of war.
There's a way to have it periodically re-authorized as well. Presidential War Powers are the basis for our involvement in Iraq and Afghanistan.
After almost a decade of continuing major military involvement in two countries, I think we should re-examine the War Powers Acts. Perhaps put a limit on the number of times it can be extended, or something similar.
